(Cl. 155-515) The present invention relates to supporting longitudinal flange 1 secured by means of transconstructions for saddles for bicycles, motor cyverse bolts 8 to a carrier device comprising two cles or the like comprising a hollow saddle body support plates 9 engaging each side of said longiof rubber or other elastic material having alongitudinal flange I. Said support plates 9, which tudinal flange of substantially the same length as may be of substantially L-shaped cross section, 5 said saddle body extending downwardly from the may be formed in such a manner that their base surface portion of the saddle body. breadths on each side of the flange I and conse- One object of the invention is to provide a quently the breadths of the supporting surfaces supporting construction for saddles of the above for the base surface of the saddle body increase 10 mentioned type, which simultaneously forms a towards the rear portion of the saddle body, so 101 reinforcement of the saddle body. For this purthat the stability of the saddle is essentially inpose I provide carrier plates for the base surface creased without the elastic properties of the sadportion of said saddle body of angle shaped cross dle being detrimentally influenced. It is thus section and substantially the same length as said possible by varying the breadth and configural5- flange on each side of the flange, a longitudinally tion of the surfaces of the support plates 9, on 1.5;-

the following description and claims. The longitudinal flange I has a downwardly In the accompanying drawings two embodiopening groove in its base surface, in which groove ments of the invention are illustrated by way of a rail 4 or the like isinserted.

suitable bore l l in the rail 4 the saddle may obviously be placed in a desired position in the longitudinal direction. Furthermore, the saddle may be swung on the bolt l3 into a more or less inclined position and fixed in such a position through tightening of the bolt l3 and a screw l9 provided in one branch of the saddle post l2 and adapted to cooperate with one side of the projection ll) of the rail 4.

In the embodiment illustrated in Figs. 4 and 5 the rail 4 has two downwardly directed projections 2| forming a fork, which embraces a longitudinal rail 22 formed at the upper end of the saddle post I2. The bolt I3 is inserted in openings in the projections 2| and the support plates 9 are provided with projections 23 one of which may be folded as at 24 for locking the head I! of the bolt I 3. The rail 22 is provided with a number of openings 25, so that the saddle may be secured in different positions. A lock screw 19 is provided in one of the projections 2| by means of which the rail 4 and the saddle post l2 may be locked relatively to one another in a desired position.

The details of the invention may naturally be modified in several different ways without departing from the scope of the invention. For instance, the bores II or 25 may be replaced by longitudinal slots, the opposite edges of which might form a number of recesses corresponding to the cylindrical portion of the bolt l3. In order to secure the bolt 13 one or both support plates may be folded to form a flange 20, as illustrated in Figs. 1 and 3, for engaging the flat sides of the square or otherwise formed bolt head II, or to form a locking lip, as indicated at 24 in Fig. 5. The. engaging surfaces of the clamping device are made to contact minutely with the corresponding portions of the surfaces cooperating therewith, said cooperating surfaces on the forks or rails etc. being, for instance, knurled or provided with a number of points or the like engaging a number of notches corresponding to said In such case the lock screw l9 may be dispensed with. Instead of being secured to the saddle post the saddle may naturally be secured directly to the frame or some other part of a vehicle adapted to form a suitable support for the saddle. The cross section of the rails 4 and 22 may naturally depart considerably from the rectangular form illustrated in the drawings.

What I claim is:

1. In a supporting construction for a hollow saddle body of elastic material for bicycles, motorcycles or the like, a longitudinal flange of substantially the same length as said saddle body extending downwardly from the base surface portion of the saddle body, carrier plates for said base surface portion of angle shaped cross section and substantially the same length as'said flange secured on each side of the flange, downwardly projecting portions on said carrier. plates, a longitudinally and centrally extending rail engaging the flange, there being openings formed in said downwardly projecting portions and said rail, and a clamping bolt extending through said openings for rigidly securing the saddle supporting construction to the bicycle or the like.

2. In a supporting construction for a hollow saddle body of elastic material for bicycles, motorcycles or the like, a longitudinal flange of substantially the same length as said saddle body extending downwardly from the base surface portion of the saddle body, there being a centrally disposed longitudinal groove formed in the bottom of said flange, carrier plates for said base surface portion of angle shaped cross section and substantially the same length as said flange secured on each side of the flange, downwardly projecting portions on said carrier plates, a longitudinally and centrally extending rail engaging said longitudinal groove of the flange, therebeing also openings formed in said downwardly projecting portions and said rail, and a clamping bolt extending through said openings for rigidly securing the saddle supporting construction to the bicycle or the like.

3. In a supporting construction for a hollow saddle body of elastic material for bicycles, motorcycles or the like, a longitudinal flange of substantially the same length as said saddle body extending downwardly from the base surface portion of the saddle body, carrier plates for said base surface portion of angle shaped cross section and substantially the same length as said flange secured on each side of the flange, there being a centrally disposed longitudinal groove formed in the bottom of the flange, a longitudinally and centrally extending rail secured in said groove, a downwardly projecting longitudinally extending projection on said rail, there being also a longitudinally extending opening formed in said projection, and a clamping bolt extending transversely through said opening for rigidly securing the saddle supporting construction to the bicycle or the like.

4. In a supporting construction for a hollow saddle body of elastic material for bicycles, motorcycles or the like, a longitudinal flange of substantiallythe same length as said saddle body extending downwardly from the base surface portion of the saddle body, carrier plates for said base surface portion of angle shaped cross section and substantially the same length as saidflange secured on each side of the flange, there,

being a centrally disposed longitudinal groove formed in the bottom of the flange, a longitudinally and centrally extending rail secured in said groove, a downwardly projecting forked portion on said rail, there being also openings in said forked portion, and a clamping bolt extending through said openings for rigidly securing the saddle supporting construction to the bicycle or the like.
